Thermal radiation and Hall effects on peristaltic blood flow with double diffusion in the presence of nanoparticles

Abstract

The aim of the present research work deals with the thermal radiation and hall effects on peristaltic blood flow with double diffusive convection of gold nanoparticles through an asymmetric channel under the long wavelength and low Reynolds number assumptions. Effect of thermal radiation and double diffusion is an important aspect of research due to its application in public health potential and hall effect can be used to measure blood flow rate because the blood contains ions that constitute an electric current. Theory of peristaltic motion, the heat flux of the linear approximation and the thermal radiation are employing on the flow problems. This approximation is possible only where the temperature difference is small in the fluid flow. The mathematical modelling of the present problem includes the partial differential equations and the basic governing equations which are solved by analytical approximation method known as Homotopy Analysis Method (HAM). Solutions are obtained for velocity, temperature, solutal (species) concentration and nanoparticle volume fraction profiles. Results for velocity profile, temperature profile, pressure rise, solutal (species) concentration profile and nanoparticle volume fraction profile for different physical parameters are discussed through graphs.
